    Method of undetermined coefficients

    Is anybody familiar with the method of undetermined coefficients?

    I'm trying to solve a second order linear differential equation of the form

    y(t) = 2t + e^t.

    Would a good guess for a general form of a solution be At+Be^t?

    What on earth are you doing?! Thinking is out right.

    The students here are off all week... which leaves us staffers with a nice, quiet campus all week.

    Ha, today is my first day of thanksgiving break and I had a quiz on this stuff just yesterday.

    For all those who are curious, At+Be^t? is a good choice.
